My power steering rack for my recently acquired Pao is toast. The person that owned it before me didn't replace the torn gaitors and the shaft got rusted. Are there good used racks available? Are they the same as the K10? I know that some of the later Paos shared the Figaro rack but this is an early one with a different rack. Has anyone swapped out a Figaro rack on a Pao that had an earlier style rack? And if so, was it bolt-on? Trying to weigh my options.
